Linear Motion Q1

What is a rate?

• a quantity divided by time; how something changes

• time divided into different quantities

• a thing you use to gather leaves in your yard

• how long something stays the same

What is the definition of velocity?

• Velocity is how the acceleration changes with respect to time.

• Velocity is how time changes with respect to displacement.

• Velocity is how the speed changes with respect to time.

• Velocity is how position and direction changes with respect to time.

What is the difference between speed and velocity?

• Speed is measured in kilometers per hour, velocity is measured in meters per second.

• Speed has no direction, velocity has direction

• Speed and velocity are the same thing.

• Speed is a physical quantity, velocity is a mathematical concept.

What is the formula to calculate speed?

• Speed = Distance x Time

• Speed = Distance / Time

• Speed = Distance + Time

• Speed = Distance - Time

• 57 minutes

• 40 minutes

• 60 minutes

• 80 minutes

What is the average speed of a car that travels 200 km in 4 hours?

• 50 km/h

• 30 km/h
